Configuring SRDs

The SRDs table lets you configure up to 41 signaling routing domains (SRD) for Gateway
and SBC calls. The SRD is a logical representation of an entire SIP-based VoIP network
(Layer 5) consisting of groups of SIP users and servers. The SRD is associated with all the
configuration entities (e.g., SIP Interfaces and IP Groups) required for routing calls within
the network. Typically, only a single SRD is required (recommended) for most
deployments. Multiple SRDs are only required for multi-tenant deployments, where the
physical device is "split" into multiple logical devices. For more information on multi-tenant
architecture, see ''Multiple SRDs for Multi-tenant Deployments'' on page 351.
As the device is shipped with a default SRD ("DefaultSRD" at Index 0), if your deployment
requires only one SRD, you can use the default SRD instead of creating a new one. When
only one SRD is employed and you create other related configuration entities (e.g., SIP
Interfaces), the default SRD is automatically assigned to the new configuration entity.
Version 7.2
Description
version(s) as the Media Realm to which the Media
Realm Extension is associated. If the associated
Media Realm is assigned both an IPv4 and IPv6
network interface, you also need to assign the Media
Realm Extension with both an IPv4 and IPv6 network
interface. For example, if the associated Media
Realm is assigned only an IPv6 network interface,
you also need to assign the Media Realm Extension
with an IPv6 network interface.
Defines the first (lower) port in the range of media UDP
ports for the Media Realm Extension.
By default, no value is defined.
Notes:

You must either configure all your Media Realms with
port ranges or all without; not some with and some
without.

The available UDP port range is according to the
BaseUDPport parameter. For more information, see
''Configuring RTP Base UDP Port'' on page 203.
Defines the last (upper) port in the range of media UDP
ports for the Media Realm Extension.
Note: It is unnecessary to configure the parameter. The
device automatically populates the parameter with a
value, calculated by the summation of the 'Number of
Media Session Legs' parameter (multiplied by the port
chunk size) and the 'Port Range Start' parameter. After
you have added the Media Realm Extension row to the
table, the parameter is displayed with the calculated
value.
Defines the number of media sessions for the port
range. For example, 100 ports correspond to 10 media
sessions, since ports are allocated in chunks of 10.
By default, no value is defined.
Note: The parameter is mandatory.
